Is the Breeze LT GTX truly waterproof?

Yes. A Gore-Tex membrane lines the shoe, so it blocks rain, puddles and wet grass while letting vapor escape. Water can still enter over the collar in deep stream crossings.

How does it compare with a full hiking boot?

It is lighter and more flexible, closer to a trail runner with an ankle shaft. A full boot gives more stiffness and support under a heavy pack; this shoe suits day hikes and light loads.

Does it fit true to size?

Vasque women's hiking shoes generally run true to size, and the padded collar and tongue hold the heel in place. Try it with the socks you hike in, since thicker socks can push you up a half size.

Is the Vibram MegaGrip outsole good on wet rock?

Yes. MegaGrip is one of the better sticky rubber compounds for wet rock and roots. It grips well on mixed terrain, though mud can still pack into the lugs.

Is it good for hot weather?

The mesh upper breathes, but the waterproof membrane traps heat. It is more comfortable in cool, wet or shoulder-season conditions than in midsummer heat.
